Abstract: Provided is a mobile IPv6 fast handovers method, which includes the steps of: a) if a mobile node is moved in a layer 2, receiving a modified RS message from a mobile node in the access router, b) detecting movement of the mobile node in a layer 3 in the access router, c) if the mobile node makes a movement in the layer 3, generating CoA of the mobile node in the access router; d) performing Duplicate Address Detection in the access router to inspect uniqueness of the generated CoA; and e) transmitting a modified RA message to the mobile node in the access router. The Fast Handovers method of the present research performs fast movement detection by using layer 2 information simply and efficiently for fast handover in the mobile IPv6 and generates CoA in the access router instead of the mobile node without operations of many additional messages.

Abstract: A wireless LAN distribution system, forwarding data received from a correspondent node to a station connected to an access point, includes: a location management server (LMS) for storing and managing a mapping table as an information table storing IP addresses of stations and physical access control addresses of the access points having the stations located therein, and causing the access points to perform an IP address check for the stations located in their area; an edge router for forwarding the data to the LMS using the physical access control address of the mapping table; and an access point for checking the physical access control address of the access point and the IP address of the destination station, and forwarding the data from the correspondent node.

Abstract: Provided are a system and method for processing freight using Radio Frequency identification (RFID). The freight processing system includes: an RFID label issuing block for issuing and attaching an RFID tag storing freight identification and destination information; an RFID linking block for generating link information between a freight and a carrier; and an RFID freight identifying block for automatically identifying the freight by reading the destination information from the RFID tag attached to the freight.

Abstract: A significant drawback of the conventional XML parsers is that such parsers require relatively large software components, which causes load of a system that processes the XML documents to increase. Provided is an XML processor in which a part of XML processing is performed in a hardware manner based on independent hardware, thereby reducing computational load of a system and improving an XML processing speed, and an XML processing method performed in a system having the XML processor. The XML processor includes: a first memory storing software for performing an XML processing, variables, and values required to execute software; a hardware processing module performing a part of the XML processing in a hardware manner; a second memory employed by the hardware processing module; and a CPU controlling the XML processing by the software stored in the first memory.

Abstract: A method of automatically generating IPv6 unicast addresses in IPv6-based next-generation Internet communication environments using a telephone number of a E.164 format allocated to a telephone terminal, and a method of looking up 32-bit IPv4 addresses or 128-bit IPv6 addresses, which are previously allocated to name addresses consisted of E. 164 telephone numbers, from a DNS. An automatic creation relates to a method in which an Internet host as a sender of an IP packet creates an IP address and a search from the DNS indicates a process of looking up an IP address of a receiver. The method automatically generates an IP address of a sender based on a telephone number and a search of an IP address of a receiver using DNS.
